Wobbles in the Barriers: Arctic Oscillation (4)

This is a continuation of my series on the Arctic Oscillation / North Atlantic Oscillation. Links to background material and previous entries are at the end.

In the last entry I suggested that if you were on a bridge overlooking a swiftly flowing creek then you would notice that twigs floating in the water did not move across the current. They are carried downstream along the edge of the current. The purpose of that comparison was to demonstrate how fast-moving, concentrated flows have the effect of isolating one side of the creek from the other. This is true in the creek, and it is also true about jet streams in the atmosphere.

One way to understand the Arctic Oscillation is to think of it as the variation of an atmospheric jet stream. For the Arctic Oscillation the jet stream of interest is the southern edge of vortex of air that circulates around the North Pole (see previous entry). Air inside the vortex often has characteristics different from air outside it. Intuitively for the Arctic, there is colder air on the side toward the pole. If you look at trace gases, like ozone, they are different across the edge of the vortex. The takeaway idea is that the edge of the vortex is a barrier. It’s not a perfect barrier, but the air on one side is largely separated from the air on the other side. In this blog, I describe the difference between a strong and a weak vortex – which is the same as the difference between the positive and negative phases of the Arctic Oscillation and the North Atlantic Oscillation.

Figure 1: This figure is from the point of view of someone looking down from above at the North Pole (NP). Compare this perspective to Figure 1 in previous blog. This represents a strong, circular vortex centered over the pole, which encloses cold air, represented as blue. The line surrounding the cold air is the jet stream or the edge of the vortex.

Figure 1 shows an idealized schematic of the North Pole as viewed from above. This is the strong vortex case, when there is exceptionally low pressure at the pole. Low pressure is associated with counterclockwise rotation in the Northern Hemisphere. This direction of rotation is called cyclonic. This strong vortex case is the positive phase of the Arctic Oscillation. During this phase, the vortex aligns strongly with the rotation of the Earth, and there are relatively few wobbles of the edge of the vortex – the jet stream. I drew on the figure two points, X and Y. In this case, the point X is hot and the point Y is cold. It is during this phase when it is relatively warm and moist over, for example, the eastern seaboard of the United States.

Figure 2 compares a strong vortex and a weak vortex. In both cases, the circulation around a central point is counterclockwise or cyclonic. However, in the weak vortex case, the vortex does not align as strongly with the rotation of the Earth and there are places where the edge of vortex extends southwards. The vortex appears displaced from the pole; it is not centered over the pole.

Figure 2: Examples of a strong, circular vortex and a weak, more wavy vortex. See text for a more complete description.

Whether the vortex is stronger or weaker is determined by the atmospheric pressure at the pole. In the winter, an important factor that determines the circulation is the cooling that occurs at polar latitudes during the polar night.

What determines the waviness or wobbles at the edge of this vortex? The structure at the edge of vortex is strongly influenced by several factors. These factors include the structure of the high-pressure centers that are over the oceans and continents to the south of jet stream. One could easily imagine a strong high-pressure center over, for example, Iceland, pushing northward at the edge of the vortex. This might push a lobe of air characteristic of the middle latitude Atlantic Ocean northward. Since the edge of the vortex is something of a barrier, this high-pressure system would distort the edge of the vortex and, perhaps, push the vortex off the pole. This would appear as a displacement of the vortex and its cold air over, for example, Russia. If the high grew and faded, then this would appear as wobbles of the vortex.

Other factors that influence the waviness at the edge of the vortex are the mountain ranges and the thermal contrast between the continents and the oceans. The impact of mountains is easy to understand. Returning to the creek comparison used above, the mountains are like a boulder in the stream. The water bulges around and over the boulder; the air in the atmosphere bulges around and over the mountain ranges. The Rocky Mountains in the western half of North America are perfect examples of where there are often wobbles in the atmospheric jet stream.

Figure 3: This figure is from the point of view of someone looking down from above at the North Pole (NP). This represents a weak, wavy, wobbly vortex displaced from the pole. The vortex encloses cold air, represented as blue. The line surrounding the cold air is the jet stream or the edge of the vortex. (definition of vortex)

Figure 3 shows an idealized schematic of the North Pole as viewed from above. This is the weak vortex case, when the low pressure at the pole is not as low as average and the pressure is much higher than the strong vortex case of Figure 1. This weak vortex case is the negative phase of the Arctic Oscillation. During this phase, the alignment of the vortex with the rotation of the Earth is less prominent, and there are wobbles of the edge of the vortex – the jet stream. In this case, the point X is cold and the point Y is hot. It is during this phase where it is relatively cool and dry (but potentially snowy) over, for example, the eastern part of the United States.

These figures help to explain the prominent signal of the Arctic Oscillation discussed in the earlier entries (specifically, this blog). That is, when the vortex is weak and wobbly, then there are excursions of colder air to the south and warmer air to the north. This appears as waviness and is an important pattern of variability - warm, cold, warm, cold.

The impact of the changes in the structure of edge of the vortex does not end with these persistent periods of regional warm and cold spells. The edge of the vortex or the jet stream is also important for steering storms. Minimally, therefore, these changes in the edge of the vortex are expected to change the characteristics of how storms move. Simply, if the edge of the vortex has large northward and southward extensions, then storms take a longer time to move, for example, across the United States from the Pacific to the Atlantic Oceans. In the positive phase of the Arctic Oscillation they just whip across. In the negative phase, the storms wander around a bit. A more complete discussion of this aspect of the role of the Arctic Oscillation will be in the next entry. (Note use of dramatic tension and the cliffhanger strategy of the serial.)

 Some things to consider when evaluating an expertThe philosopher (and evolutionary biologist) Massimo Piglucci gives 5 pieces of evidence by which we can determine when someone is a trustworthy expert or not.(1) Examination of their arguments (often difficult)(2) Evidence of agreement by other experts(3) Independent evidence that the expert is indeed an expert (e.g. credentials)(4) Examination of biases the expert may have(5) Track record of the expert.

 I am only going to clarify this once. When the discourse either for or against climate change then moves into the realm of websites that repeatedly use hateful rhetoric, I lose patience and any will to be nice to anyone involved.The pindanpost repeatedly refers to those who are pro GW as "Green Nazis", accuses them of "facist eugenics" and openly supports the Galileo Movement, which their marketing director claims: "Mr Roberts said climate change science had been captured by ''some of the major banking families in the world'' who form a ''tight-knit cabal''. He said he understood that the group's views might sound strange, but claimed they were becoming increasingly popular. ''It does sound outlandish,'' Mr Roberts said. ''I, like you, was reluctant to believe it [but] there are significant things going on in Australia that people are waking up to. The UN's climate front is just a part of the overall UN 'Agenda 21', which is the sustainability program and the biodiversity program … But the biggest one's the UN agenda for global governance.'"I have zero tolerance for this line of conspiracy bull. Other notable Galileo Movement people are "Lord Christopher Monckton, Richard Lindzen, Fred Singer, Bob Carter, Ian Plimer and the Cato Institute's Pat Michaels" (all information here from desmog blog, fyi). I flatly will not play this game of UN conspiracy nonsense, Nazi allusions, and Jewish global banking conspiracy. If your blog, organization, or group supports these idiots, you are directly part of their agenda. It's not an agenda based on science, but instead one of the world's oldest conspiracies based on hatred and paranoia masquerading as science. To put it succinctly, you've been duped.Was I harsh with my rhetoric. Yes. But no more harsh then what these folks accuse AGW supporters of day after day and blog after blog. In the case of Yoboi, he has openly shown what sources he chooses to use in this "discussion" and instead of any apology, just uses the same old "I'm just showing the other side of the argument" crap. I'll be taking a break from here since I have rubbed some folks the wrong way and more so, because even when shown the basis of why I said what I said, ignore the reality of the situation.

 Press release from The University of Washington:New study explains increase in Antarctic sea iceAs the Arctic sea ice melt continues to concern many within the scientific community, it is an increase in Antarctic sea ice that has raised questions. UW research scientist and associate professor Jinlun Zhang recently released a study examining the reason for this phenomenon.Although global sea ice is still in decline, certain areas of Antarctica have experienced an increase in sea ice thickness. According to Zhang’s research, this trend is due to an increase in winds in the southern oceans that decrease surface air temperature, causing the sea ice to ridge more often.Ignatius Rigor, UW research scientist and climatologist at the UW’s Polar Science Center, says that scientists shouldn’t just look at one place, such as the Arctic, and decide that sea ice is in decline. The key, to him, is whether those same decreases happen worldwide. “Climate change is a global thing, and we need to understand how the climate is changing over the whole globe and [whether] it is consistent with global warming,” Rigor said. “[Zhang’s research] makes a lot of sense. One of the things we expect in a warming planet is a change in weather.”Zhang’s model shows that the change in the southern wind’s pattern causes more pressure to be exerted on the sea ice below and creates thicker layers. However, even in layers that had an increase in thick ice, there was no large change in medium or thin ice production.Axel Schweiger, a climatologist at the Polar Science Center who has worked with Zhang on numerous occasions, believes that others will begin basing their work on Zhang’s model-based discovery. “I think the paper offers a potential answer to the problem that has been bugging the science community for a while: why Antarctic sea ice could be increasing in a warming world,” Schweiger said. Sea ice isn’t increasing uniformly among the different Antarctic regions, as some is in decline. According to Zhang’s research, this difference is possibly due to the variability of surface air temperature of different Antarctic regions.

 Quoting 454. MisterPerfect:'Wind Turbine Syndrome' Blamed for Mysterious Symptoms in Cape Cod TownOct. 21, 2013 By SUSAN DONALDSON JAMESDigital Reporter via Good Morning AmericaSue Hobart, a bridal florist from Massachusetts, couldn't understand why she suddenly developed headaches, ringing in her ears, insomnia and dizziness to the point of falling "flat on my face" in the driveway. "I thought I was just getting older and tired," said the 57-year-old from Falmouth. Months earlier, in the summer of 2010, three wind turbines had been erected in her town, one of which runs around the clock, 1,600 feet from her home. "I didn't put anything to the turbines -- we heard it and didn't like the thump, thump, thump and didn't like seeing them, but we didn't put it together," she told ABCNews.com. Hobart said her headaches only got worse, but at Christmas, when she went to San Diego, they disappeared. And she said the same thing happened on an overnight trip to Keene, N.H. "Sometimes at night, especially in the winter, I wake up with a fluttering in the chest and think, 'What the hell is that,' and the only place it happens is at my house," she said. "That's how you know. When you go away, it doesn't happen."Hobart and dozens of others in this small Cape Cod town have filed lawsuits, claiming that three 400 feet tall, 1.63 megawatt turbines (two owned by the town and one owned by Notus Clean Energy) were responsible for an array of symptoms. A fourth, much smaller turbine, is owned by Woods Hole Research Center, but it receives fewer complaints. The wind turbines have blown up a political storm in Falmouth that has resonated throughout the wind energy industry. Are these plaintiffs just "whiners," or do they have a legitimate illness? "It goes all day and night. My initial take was that she was being a hypochondriac, but I went to their house two years ago with a little skepticism and within 10 minutes of being in the house, I could feel it and hear it." -- Brian Mannal, lawyer for Sue Hobart In 2011, a doctor at Harvard Medical School diagnosed Hobart with wind turbine syndrome, which is not recognized by the Centers for Disease Control and Prevention. The name was coined by Nina Pierpont, a John Hopkins University-trained pediatrician, whose husband is an anti-wind activist, criticizing the economics and physics of wind power. Pierpont, who lives in upstate New York, calls wind turbine syndrome the green energy industry's "dirty little secret." She self-published "Wind Turbine Syndrome" in 2009, including case studies of people who lived within 1.25 miles of these "spinning giants" who reportedly got sick. But her wind-turbine research has been criticized for improper peer review (Pierpont reportedly chose her reviewers), and for its methodology -- small sample size, no control group and the fact that she did not examine her subjects or their medical records but interviewed them by phone. Neither Pierpont nor her husband, Calvin Luther Martin, responded to ABCNews.com's request for comment. Hobart and her husband, Edward, filed a nuisance claim last Feb. 5 in Barnstable Superior Court against Notus Clean Energy and its owner, Dan Webb. According to the Hobarts' lawyer, Democratic State Rep. Brian Mannal, they are seeking between \$150,000 and \$300,000 in damages for loss of value of their home, and for medical bills. They filed an earlier nuisance complaint against the town in July 2012, but the judge granted the defendants' motion to dismiss on Dec. 3, 2012. "The heart of the issue is that they have been pushed off their land," said Mannal. "They have erected these enormous industrial-scale turbines -- larger than a 747 -- in close proximity to residences. They have had to leave their house because they couldn't live there anymore."continued..If you really believe AGW is made up, well then I'm assuming you're one of those who understands climate change and the anthropogenic effects of CO2 from the likes of WUWT? ;-)The truth is--and has been documented by NASA and thousands of climate scientists is that the globe is warming, and rapidly.

 Attack of the Sock PuppetsLinkHmmm:NPR media reporter David Folkenflik writes in his forthcoming book Murdoch’s World that Fox News’ public relations staffers used an elaborate series of dummy accounts to fill the comments sections of critical blog posts with pro-Fox arguments.In a chapter focusing on how Fox utilized its notoriously ruthless public relations department in the mid-to-late 00’s, Folkenflik reports that Fox’s PR staffers would “post pro-Fox rants” in the comments sections of “negative and even neutral” blog posts written about the network. According to Folkenflik, the staffers used various tactics to cover their tracks, including setting up wireless broadband connections that “could not be traced back” to the network.I think one can safely assume that Fox News wasn’t the only organization employing sock puppets. Some commenters on various blogs, including this one, are pretty obviously professional trolls. I’ve banned some of them — and banned what were obviously the same people coming back under a variety of names.In general, if your reaction to some comments is that nobody could really be that stupid, it may be that you are just underestimating the power of stupidity — but it may also be that nobody is, in fact, that stupid, but that someone has been employed to play stupid for fun and profit.

 Enbridge tar sands pipeline threatens Great LakesAfter two years of pressing pipeline regulators to release inspection photos and videos of the 60-year-old Enbridge pipeline that carries tar sands oil through the Straits of Mackinac, the National Wildlife Federation took it upon themselves to inspect the pipeline.Unfortunately, their footage is cause for concern and shows why this pipeline is one of the greatest threats to the Great Lakes.The footage shows pipelines suspended over the lakebed, some original supports broken away (indicating the presence of corrosion), and some sections of the suspended pipelines covered in large piles of unknown debris. This visual is evidence that our decision makers need to step in and demand a release of information from Enbridge and PHMSA.Heightening our concern around this pipeline and the company that owns it: despite having cleared our dive work with the U.S. Coast Guard, several Congressional members, and Homeland Security, our staff and the dive crew had uncomfortable interactions with Enbridge representatives. As soon as our team set out on the water, we were quickly accompanied by an Enbridge crew that monitored our every move. This monitoring did not stop at the surface: Enbridge also placed a Remote Operated Vehicle (ROV) into the water to watch our team.TreeHugger.com

 Quoting 470. Naga5000:Quoting 465. BaltimoreBrian:Wow yoboi is a popular blogger! He'll probably pass the comment count in my entry by Wednesday. However I believe in quality over quantity ;)My current entry is about 200 days old.I'm done there. We have escalated into "Green Nazis" from the pindanpost.com, who also support the same crazies involved in Jewish conspiracy climate craziness. Too insane for my brain.Well, as long as everyone is having fun over there. Personally, I think it's giving the deniers more airtime than they really deserve, but c'est la vie. There were some good attempts to set the record straight over there today. However, like the denialist playbook reads, it's all just about stringing people along to help amplify the denialist message that there's a "debate" about human-induced climate change, and thus fueling the incorrect notion that there's two sides to the issue. As a side note, at least I learned that ncstorm watched the Richard Alley videos, yet still remains unconvinced. That is a real shame, because I think those videos are the best, most straightforward explanation of how we know that humans are responsible for the increase in CO2 and subsequent rise in global temperatures.I also learned that he/she has declared that there's nothing that can be said to convince them of these facts. That, too, is a real shame. Basing your personal conclusions on a subject of which you have little to no knowledge or understanding is tantamount to bearing false witness. And THAT transgression is one of the most unforgivable according to some faiths.

 Quoting 473. BaltimoreBrian:Flag the comments with the anti-semite link a and post about it on sensitivethug's blog. See if they keep tolerating anti-semitism from yoboi again.None of the links discuss it directly, but other "infamous" articles from them use terms like "Green Nazi" and they support writers from the Galileo Movement. So no obvious violation, much like the case from Veteran's Today. Anyways, I won't pursue it any further. I am simply taking my ball and going home.

 Naga5000, yoboi linked to anti-semite websites last summer. One said that global warming was a Jewish conspiracy, from the Zionist Occupied Government website. The other was from a hate group listed on the Southern Poverty Law Center. It's clear what he believes in and that the wunderground moderators and administrators do not care about anti-semitism. I chose not to honor yoboi with my august company due to his past record of posting anti-semitic links. That means I haven't seen what he posted. Given yoboi's record, though.....

However I believe in quality over quantity ;)My current entry is about 200 days old.I'm done there. We have escalated into "Green Nazis" from the pindanpost.com, who also support the same crazies involved in Jewish conspiracy climate craziness. Too insane for my brain.

 Fire and climate change: don’t expect a smooth ride "With fires still burning across New South Wales, it’s time to have a look at the role climate change might have played. Are the conditions we’re seeing natural variation, or part of a long term trend?In fact, it doesn’t have to be one or the other.Has bushfire risk increased due to climate change?In research I did with colleagues earlier this year we looked at the Fire Danger Index calculated by the Bureau of Meteorology, and compared how it changed compared to temperature over time in Victoria.South-east Australia saw a temperature change of about 0.8C when we compared temperatures before 1996 and after 1997. We know that it got drier after 1997 too.We then compared this data to the Forest Fire Danger Index, to see if it showed the same pattern. We analysed fire data from nine stations in Victoria and did a non-linear analysis.We found that fire danger in Victoria increased by over a third after 1996, compared to 1972-1996. The current level of fire danger is equivalent to the worst case projected for 2050, from an earlier analysis for the Climate Institute.While it’s impossible to say categorically that the situation is the same in NSW, we know that these changes are generally applicable across south-east Australia. So it’s likely to be a similar case: fire and climate change are linked.What is “non-linear” change?Climate science has been playing with a paradigm that long-term changes are gradual, and that short-term changes are simply natural climate variability. But there’s another hypothesis that climate change and climate variability actually combine.When you analyse long historical time series of temperature, plus climate change from modelled data, it actually goes up like a staircase. The “El Niño of the century” we saw in 1997-98 was one of these steps in the staircase.It’s physically impossible for climate change to be entirely gradual, and for natural variability to act independently of that. That’s like saying that some of the heat in the atmosphere is climate change heat, and some is variability heat, and that they behave differently.This also relates to the so-called hiatus. This hiatus is normal, and what we’d expect from a climate that evolves in a non-linear manner.The models do predict these steps, even if some people claim they don’t. Model data shows periods up to 20 years when there is little or no increase in warming.What’s happened to temperature and rainfall in south east Australia?"...Read more at The Conversation >>Link

 Why the Media Is Right to Toss Climate Deniers' Opinions"Earlier this month, the Los Angeles Times officially confirmed the paper is no longer running letters to the editor that deny the scientific conclusion that climate change is a reality and is caused mainly by human activities. Prior to this, the magazine Popular Science went even further and completely turned off the comments section for its entire website, stating quite eloquently that, "Everything, from evolution to the origins of climate change, is mistakenly up for grabs again. Scientific certainty is just another thing for two people to 'debate' on television. And because comments sections tend to be a grotesque reflection of the media culture surrounding them, the cynical work of undermining bedrock scientific doctrine is now being done beneath our own stories, within a website devoted to championing science."The L.A. Times editor stated the paper's reasoning as, "Letters that have an untrue basis (for example, ones that say there's no sign humans have caused climate change) do not get printed."The Sydney Morning Herald has subsequently announced it also won't allow climate deniers to "misrepresent facts" on climate science in letters - an especially powerful case given the terrifying fires ravaging Australia against a backdrop of continuing broken heat records. As the former Editor of DeSmogBlog, most of the climate deniers and self-proclaimed skeptics I have encountered over the years have been paid by Exxon, the Koch brothers or other such industry interests, making a good living as fake experts for hire. They are manipulators of the truth."...Read more at DeSmogBlog >>

 Quoting 454. MisterPerfect:'Wind Turbine Syndrome' Blamed for Mysterious Symptoms in Cape Cod TownOct. 21, 2013 By SUSAN DONALDSON JAMESDigital Reporter via Good Morning AmericaSue Hobart, a bridal florist from Massachusetts, couldn't understand why she suddenly developed headaches, ringing in her ears, insomnia and dizziness to the point of falling "flat on my face" in the driveway. "I thought I was just getting older and tired," said the 57-year-old from Falmouth. Months earlier, in the summer of 2010, three wind turbines had been erected in her town, one of which runs around the clock, 1,600 feet from her home. "I didn't put anything to the turbines -- we heard it and didn't like the thump, thump, thump and didn't like seeing them, but we didn't put it together," she told ABCNews.com. Hobart said her headaches only got worse, but at Christmas, when she went to San Diego, they disappeared. And she said the same thing happened on an overnight trip to Keene, N.H. "Sometimes at night, especially in the winter, I wake up with a fluttering in the chest and think, 'What the hell is that,' and the only place it happens is at my house," she said. "That's how you know. When you go away, it doesn't happen."Hobart and dozens of others in this small Cape Cod town have filed lawsuits, claiming that three 400 feet tall, 1.63 megawatt turbines (two owned by the town and one owned by Notus Clean Energy) were responsible for an array of symptoms. A fourth, much smaller turbine, is owned by Woods Hole Research Center, but it receives fewer complaints. The wind turbines have blown up a political storm in Falmouth that has resonated throughout the wind energy industry. Are these plaintiffs just "whiners," or do they have a legitimate illness? "It goes all day and night. My initial take was that she was being a hypochondriac, but I went to their house two years ago with a little skepticism and within 10 minutes of being in the house, I could feel it and hear it." -- Brian Mannal, lawyer for Sue Hobart In 2011, a doctor at Harvard Medical School diagnosed Hobart with wind turbine syndrome, which is not recognized by the Centers for Disease Control and Prevention. The name was coined by Nina Pierpont, a John Hopkins University-trained pediatrician, whose husband is an anti-wind activist, criticizing the economics and physics of wind power. Pierpont, who lives in upstate New York, calls wind turbine syndrome the green energy industry's "dirty little secret." She self-published "Wind Turbine Syndrome" in 2009, including case studies of people who lived within 1.25 miles of these "spinning giants" who reportedly got sick. But her wind-turbine research has been criticized for improper peer review (Pierpont reportedly chose her reviewers), and for its methodology -- small sample size, no control group and the fact that she did not examine her subjects or their medical records but interviewed them by phone. Neither Pierpont nor her husband, Calvin Luther Martin, responded to ABCNews.com's request for comment. Hobart and her husband, Edward, filed a nuisance claim last Feb. 5 in Barnstable Superior Court against Notus Clean Energy and its owner, Dan Webb. According to the Hobarts' lawyer, Democratic State Rep. Brian Mannal, they are seeking between \$150,000 and \$300,000 in damages for loss of value of their home, and for medical bills. They filed an earlier nuisance complaint against the town in July 2012, but the judge granted the defendants' motion to dismiss on Dec. 3, 2012. "The heart of the issue is that they have been pushed off their land," said Mannal. "They have erected these enormous industrial-scale turbines -- larger than a 747 -- in close proximity to residences. They have had to leave their house because they couldn't live there anymore."continued.."Hookah Pipe Syndrome" also causes mysterious type symptoms.....

 Quoting 456. Patrap:Trust me, those 250K Volt High Tension Wires are actually therapeutic, don't worry bout it''Taint the same thing at all.There are NO credible scientific studies linking EM fields, esp. at the levels found near power lines, to any health effects. Good thing, too, considering the EM bubble that most people walk around in nowadays. If there were, folks would be dropping like flies on the streets every day.However, there ARE good scientific studies that link chronic low-frequency noise to health effects. There is a brief mention of same near the end of the article.Will try to write a more detailed response later.
